INTRODUCTION Seamounts are considered underwater features –usually of volcanic origin or aassociated to tectonic activity– rising from the seafloor and peaaking below the sea level. From a geological perspective, these underwater elevations have been originally described as greater than 1,000 m in relief (Menard, 1964; International Hydrographic Organization, 2008). However, since no obvious ecological rationale seems to sustain the size-based criteria (Pitcher et al., 2007; Wessel, 2007), later definitions contemplate any underwater elevation rising more than 100 m (Staudigel et al., 2010; Morato et al., 2013). Although scientific knowledge on seamounts is very sparse, the importance of the ecosystems associated to these elevations has been recently recognized by scientist, management authorities, the fisheries industry and conservationist (Stocks et al., 2012). The reason of its unusual high species richness and biomass relies on two main factors: 1. Seamounts are generally formed by hard substrata –which is absent in the surrounding flat abyssal plains– that provides the suitable ruggedness and habitat complexity for tthe colonization and growth of diverse fauna (Santos & Morato, 2009). 2. Seamounts induce changes in the circulation of water masses, producing tides, eddies (so-called Taylor Columns) and upwellings (White et al. 2007). These variations concenttrate zooplankton and fish, and they increase the vertical exchannge in the water column, enhancingg primary production, food supply and zooplankton growth rates (Santos & Morato, 2009; IUCN, 2013). The combination of these characteristics enriches benthic and pelagic communities around seamounts, constituting them as hotspots of biological diversity and production (Morato et al., 2010)). The enhanced local currents originate a highly productive system, supplying organic matter to benthic suspension feeders. These organisms, typically deep-waater corals, spponges, hydroids and asciddians, are able to create intricate struuctures that contribute to the habitat complexity, and thus sustain a wide variety of species living in close association (Gubbay, 2003; Rogers, 2004; Probert et al., 2007). These associated species are represented by deep-sea and pelagic ones, and often hold a high commercial value such as orange roughy, alfonsino, tuna and sharks. Seamounts also concentrate other animals such as highly migratory species like cetaceans, seabirds and pinnipeds, which are also regular hosts in this environnment (IUCN, 2013). According to the geographic distances between seamounts and their special hyddrrographic conditions, different hypothesis have raised. The “Seamount Endemicity Hypothesis” (SMEH) states ideas of faunal isolation and the presence of higghly endemic taxa (McCain, 2007). Oppositely, when seamounts lie close to the continental shelf or occur in chains, studies suggest tthat seamounts act as stepping stones for fauna, enabling exchange and connectivity fluxes of populattion in the deep abyss (Hubbs, 1959; Shank, 2010; Clark et al., 2012). On the other hand, seamountts commonly present different Vulnerable Marine Ecosystems (VME) as coral gardens, deep-sea sponnge aggregations and hydrothhermal vents. These ecosystems aree known to be of immense importance and value for deep- sea and the biodiversity they contain, and are currently threaten by anthropic practices (Auster, 2011). 3 1.1. Seamounts in Europe Recent studies estimate the total number of large seamounts (<1,000 m height) worldwide from 25,000 to 140,000 and small ones (>100 m height) from 125,000 to 25 million approximately (Morato et al., 2013). European basins present some of these features, mainly in the Atlantic but also in the Mediterranean waters. In the case of NE Atlantic, although OSPAR’s database contemplates a total of 104 seamounts –spread out in Areas Beyond National Jurisdiction (ABNJ) and EEZ from Norway, Sweden, Faroe Islands, UK, Ireland, France, Spain and Portugal– a total of 557 large seamount-like features have been inferred through bathymetric grids (Morato et al., 2013). Most of them lie along the Mid Atlantic Ridge (MAR), between the Charlie-Gibbs Fracture Zone, south from Iceland and the Hayes Fracture Zone (Azores latitude). There are also seamount clusters situated on the Madeira-Tore Rise, along the south west of the Rockall Bank and west of Portugal (Gubbay, 2003). In Mediterranean waters, underwater elevations were estimated to be 59 (Kitchingman et al., 2007), concentrated mainly in the Alboran and Tyrrhenian seas (OCEANA, 2011). However, recent studies have raised the number up to 101 (Morato et al., 2013). Laminaria ochroleuca © OCEANA / Carlos Suárez Scorphaena scrofa © OCEANA Kelp forest – Gorringe Bank © OCEANA 4 1.2. Legal framework The depletion of marine resources in coastal waters and continental shelves, coupled with the increase of technology and fish demand has led the industry to seek for new fishing grounds further out and deeper into the oceans (IUCN, 2013). These new places are often situated close to seamounts, taking advantage of the aforementioned values that occur in these formations. Due to the deleterious effects on seamount’s VMEs caused by destructive fishing gears (Clark et al., 2010) and the unfavorable ecological characteristics of deep-sea species for exploitation (e.g. long turn-over and low reproductive rates), concerns have been raised amongst the international community and several European Authorities have –or are intended to– declared measures aiming to alleviate the damage. UNGA Resolution 61/105 calls upon States to “(…) to sustainably manage fish stocks and protect vulnerable marine ecosystems, including seamounts, hydrothermal vents and cold water corals, from destructive fishing practices recognizing the immense importance and value of deep sea ecosystems and the biodiversity they contain;”. UNGA Resolution 64/72 calls upon States to “(…) implement the 2008 International Guidelines for the Management of Deep-sea Fisheries in the High Seas of the FAO (“the Guidelines”) in order to sustainably manage fish stocks and protect vulnerable marine ecosystems, including seamounts, hydrothermal vents and cold water corals, from destructive fishing practices (…)”. FAO International Guidelines for the Management of Deep-Sea Fisheries in the High Seas includes “summits and flanks of seamounts, guyots, banks, knolls, and hills” as examples of topographical, hydrophysical or geological features, including fragile geological structures, that potentially support VMEs species groups or communities. These guidelines aim to serve as a reference to help States and RFMO/As in implementing appropriate measures for the management of deep-sea fisheries in the high seas. OSPAR has enlisted “seamounts” as “Threatened and/or declining habitat”. Moreover, a Recommendation on seamounts’ management is pending to be approved early in 2014. Barcelona Convention’s “Dark Habitats Action Plan” considers especial habitats and species associated to seamounts. This tool has been endorsed at the end of 2013 during the COP Meeting. NEAFC has adopted temporal fishing closures to vessels with bottom-contacting gears in large NE Atlantic regions (Mid-Atlantic Ridge, Reykjanes Ridge, etc.) including several seamounts (e.g. Altair and Antialtari seamounts), in order to protect VMEs in line with ICES Recommendation. GFCM has included actions such as “Develop mid-term research programmes to identify conservation measures and to promote sustainable use of deep-sea habitats (seamounts, canyons and deep coral populations) and related fishing stocks” and “Collect environmental and biological information on marine seamounts” on its Programme of Work for the Intercessional Period 2013-2014. Most of the aforementioned management measures involve different underwater elevations including seamounts and banks. In the NE Atlantic, that is the case of Charlie-Gibbs Fracture Zone Marine Protected Area (MPA) that presents seamounts as Minia, Hecate and Farday; and Mid Atlantic Ridge North of the Azores MPA, which includes Gnitsevich seamount. Other seamounts protected under OSPAR MPA Network are: Anton Dohrn, Altair, Antialtair, Milne, L’Esperance, Seldo, Dom João de Castro, Crumb, El Cachucho, and Josephine. Some of them coincide with protected areas designated by other Authorities, as for example Altair and Antialtair seamounts, closed to bottom-fisheries by 5 NEAFC, and El Cachucho, designated under Natura 2000 Network. Further Natura 2000 nominations are to be designated in underwater features like Galicia and Concepción Banks in 2014. In the Mediterranean Sea, only the biggest seamount (Eratosthenes) is currently protected under a “Fisheries Restricted Area” from GFCM (REC.GFCM/2006/3). Further protections are planned to be implemented in 2014 as it is the case of Chella Bank in Spanish national waters under Natura 2000, and the seamounts of Mallorca Channel (Ausias March and Emile Baudot), whose summits (above 200

A total of 32 transect counts were per- formed. Habitats sampled included sandy bottom, rocky boulders, vertical walls and rocky outcrops. Species richness, diversity, density, trophic structure, size and spatial organization were documented for the fish assemblages. Forty-four species from 23 families were encountered; 32% belonged to Sparidae (10) and Labridae (four). The greatest species richness (25) was observed in rocky boulder habitat at 10–15 m depth, while the lowest (five) occurred over a deeper sand habitat. The greatest density (760Á5 individuals per 100 m2) was recorded over rocky outcropping (20–25 m deep), and the lowest of 11Á6 individuals per 100 m2 was over a sand bottom at 10–15 m depth. Thalassoma pavo, Abudefduf luridus and Chromis limbata had higher densities on hard bottoms, while Heteroconger longissimus was the most abundant species in sand bottom habitats.

G. 1, Davies Jaime 2 1 School of Natural Sciences; Trinity College Dublin; Dublin Ireland 2 Ifremer; Département LEP; Centre de Brest; Plouzané France * Corresponding author : Angela Stevenson, email address : [email protected] Abstract : Predation and competition are highly influential factors determining space use in foraging animals, and ultimately contribute to the spatial heterogeneity observed within habitats. Here we investigated the influence of competition and predation on space and resource use via continuous video transect observations – a tool that has not previously been employed for this purpose. This study therefore also evaluates video data as a pragmatic tool to study community interactions in the deep sea. Observations were compiled from 15 video transects spanning five submarine canyons in the Bay of Biscay, France. Substrate choice, positioning on the coral, echinoid aggregate size, and the presence/absence of predators (e.g. fish and decapods) as well as competitors (both inter- and intra-specific) were recorded. Two dominant co-existing echinoid taxa, echinothurids and Cidaris cidaris (3188 total observations), were observed in the study. For the echinothurids, no significant trends were detected in the inter- and intra-specific competition data. For Cidaris cidaris, significant shifts in substrate use were correlated to the presence of inter-specific competitors (echinothurids), whereby an increase in dead coral substrate usage was observed.

  • INTERTIDAL ZONATION Introduction to Oceanography Spring 2017 The
    INTERTIDAL ZONATION Introduction to Oceanography Spring 2017 The Intertidal Zone is the narrow belt along the shoreline lying between the lowest and highest tide marks. The intertidal or littoral zone is subdivided broadly into four vertical zones based on the amount of time the zone is submerged. From highest to lowest, they are Supratidal or Spray Zone Upper Intertidal submergence time Middle Intertidal Littoral Zone influenced by tides Lower Intertidal Subtidal Sublittoral Zone permanently submerged The intertidal zone may also be subdivided on the basis of the vertical distribution of the species that dominate a particular zone. However, zone divisions should, in most cases, be regarded as approximate! No single system of subdivision gives perfectly consistent results everywhere. Please refer to the intertidal zonation scheme given in the attached table (last page). Zonal Distribution of organisms is controlled by PHYSICAL factors (which set the UPPER limit of each zone): 1) tidal range 2) wave exposure or the degree of sheltering from surf 3) type of substrate, e.g., sand, cobble, rock 4) relative time exposed to air (controls overheating, desiccation, and salinity changes). BIOLOGICAL factors (which set the LOWER limit of each zone): 1) predation 2) competition for space 3) adaptation to biological or physical factors of the environment Species dominance patterns change abruptly in response to physical and/or biological factors. For example, tide pools provide permanently submerged areas in higher tidal zones; overhangs provide shaded areas of lower temperature; protected crevices provide permanently moist areas. Such subhabitats within a zone can contain quite different organisms from those typical for the zone.
